In a typical domestic or light commercial installation with a 6 kA or 10 kA upstream main breaker, this 3 kA unit is suitable for final circuits where the fault level at the board is known to be below that threshold. Energy limiting class 3 (cite:) means it limits let-through energy under fault conditions to a level that coordinates with downstream equipment, reducing arc-flash risk and cable damage. The neutral conductor switching function (cite:) confirms the neutral pole opens and closes with the phase, which is required in some national wiring rules for single-phase final circuits. The breaker occupies 2 width units (approx. 36 mm) on a standard DIN rail, with a 55 mm installation depth that fits flush in most enclosure back panels. The IP20 housing requires no additional finger-duct clearance for the terminals. The AC/DC voltage type (cite:) means the internal arc-extinction chamber is designed for both alternating and direct current — though the 3 kA rating applies at 240 V AC; derate for DC per the manufacturer's curve if used on a DC bus.","metaTitle":"Siemens SENTRON 5SQ2570-0KA10 MCB, 10A C-Curve, 1P+N, 3kA","metaDescription":"Siemens SENTRON 5SQ2570-0KA10 miniature circuit breaker, 10 A, C-curve, 1P+N, 3 kA breaking capacity per EN 60898, 240 V AC, IP20.
